There are reasons prices differ and can arrange from screwin you to more functional and better quality parts (chinese vs American).
The Porter-Cable 7424 is speed (RPM/OPM) adjustable. Also, I believe someone else mentioned that the Mequiars buffer/polisher is a Porter-Cable unit that's rebadged.

The 7424 that I own is a polisher. I read thru the entire instruction manual and no where is the word "buffer" used, only polisher.

Just use a buffing pad with it instead of a polishing pad...

At the risk of sounding stupid, what is the difference between a buffer and a polisher.
Aren't they the same?

i use two different ones....a straight buffer/polisher and the griots orbital unit.........i use the straight buffer polisher for deep cleaning and then the orbital for final polishing and waxing.....i bought an assortment of foam pads of different densities...they are all hook and loop and i interchange them.

if you are scared of ruining your paint the griots is a good unit and it will stop turning before you have ruined your paint....the straright buffer polisher will burn through paint in you are not careful.

For those keeping score ( ), the Griot's unit is a "random orbital polisher" (also called a "random orbital buffer") and is the Porter-Cable 7336 (which is the same as the 7424, but with a Velcro backing plate and a larger counterweight, both of which can be bought separately and installed on the 7424 to turn it into a 7336 if you like). The "straight buffer/polisher" that you're referring to is a "rotary/direct-drive buffer" (or polisher) and, because it can burn your paint, needs to be used with care.

I bought the 7424 on sale and it came with the 6" counterweight at no extra charge, and that turned the 7424 into pretty much the same unit as the Griot's unit. I also bought a kit of foam polishing pads and a quick disconnect adapter to make changing the pads easy. I don't need the velcro backing plate because of the polishing pad kit that I bought, but I could've bought it too (and then I'd have a 7336, same as Griot's sells). Oh yeah, the Griot's comes with a plastic case - I bought a metal case for, I think, $15. So I ended up getting a little better setup than the Griot's for less money.

The only difference is the pad you use.

But there are different types of buffer/polishers - random orbital vs. rotary (direct-drive).

Excellent replies from all, as usual.
I went to local Home Depot (no Lowe's nearby that I know of) and they had no Porter Cable polishers.
The manager of the tool department there started talking to me and asked what I was going to polish and it turns out he owns a 76 Vette and told me to buy the Griots polisher so that is what I ordered with the Red and the Orange foam pad with the velcro back.
VCuomo, excellent description of the differences.
Anxious to put a coat of wax or two on my baby as it has only been waxed once since the new paint job last year.
The Benz will get waxed too and then wifey's car. Need to play with the new toy.
MY son just bought new black Silverado pickup and he already wants to borrow the polisher and it isn't even here yet.
Thanks for all the advice,
Kurt
